The profit depends on the desired currency the OP is expecting. The question is when will he cash out, will he hold his altcoins he traded Bitcoin for on a long-term, will he later regain the Bitcoin or something else. I am looking at the altcoin trading in a long term.
To me, it doesn't matter if the certain altcoins or the Bitcoin will drop when the market is the big fluctuation phase because I know that the altcoin I have invested in has the possibility to reach my desired goals.
If the OP is trading for the FIAT and using decentralized currencies for the daily living then the amount loses in a couple of days when the market falls means significantly to him and he cannot afford himself to wait a couple of days more for a market to regain itself. Because of that, I support people that have their day jobs and they do investment as a hobby.
Those who are depending on the market trades without some background financial capability are taking a high risk of losing everything.
